Comment: I'm not going to do a full review of all 49 references, but patents and interviews aren't independent, Broadway world isn't reliable, and neither are ScienceDirect topic pages. Most of the scientific articles don't contain in-depth coverage of Cold Jet — reference 4 comes the closest, but even that isn't really about Cold Jet, it just compares it to a bunch of other products. Reference 5 looks like a press release to me. Ref 13 is about the Particle Control System, not about Cold Jet. This doesn't convince me that an in-depth review of all 49 would show notability. Your best bet is to select the three sources that you think best meet the requirements at WP:42, and that way it'll be easier for a reviewer to tell you whether Cold Jet is notable or not.

Cold Jet operates manufacturing facilities in the United States, Denmark, and Poland. The company has been featured on the History Channel series Modern Marvels[5] and the National Geographic series Showdown of the Unbeatables.[6]
History
Cold Jet was founded in 1988 in Loveland, Ohio. The company introduced a single-hose dry ice blasting system, which uses a single hose to deliver compressed air and dry ice particles to a surface. The original patents for this technology were awarded to David Moore of CRYOBLAST Inc., a predecessor company to Cold Jet, in 1986 (U.S. Patent 4,617,064) and 1988 (U.S. Patent 4,744,181).[1][2] The single-hose design was central to the technology's commercial viability, allowing dry ice particles to achieve higher velocities throughout the entire hose length compared to two-hose systems, thereby increasing the kinetic energy of particles at impact.[7][3]
Dry ice blasting technology traces its origins to the 1940s, when the United States Navy began experimenting with dry ice blasting for degreasing applications in 1945.[4] In the 1970s, Lockheed Corporation further developed dry ice blasting as a method for removing paint from aircraft.[8]
Technology innovations
Cold Jet has introduced several patented technologies and innovations in dry ice blasting.
In 1997, Cold Jet patented the Multiple Expansion Reflection Nozzle (MERN) technology.[9] This nozzle design uses a single contoured wall opposite a flat reflection wall to direct supersonic airflow and dry ice particles, departing from symmetrical nozzle configurations. The design is intended to minimize particle breakage and sublimation before impact.[10]
In 2012, Cold Jet patented variable fragmenting technology[11] to control dry ice particle size during blasting. The system uses adjustable pins positioned downstream of the nozzle throat that can be rotated to fragment pellets into variable sizes, allowing operators to select whole pellets, mixed sizes, or fine fragments to match application requirements.
In 2019, Cold Jet patented and introduced the Particle Control System,[12] which enables operators to select specific particle sizes. The technology cuts standard 3 mm dry ice pellets into particles ranging from 0.3 mm to 3 mm, allowing operators to match particle size to specific surface or substrate requirements.[13]
Acquisitions and investments
In 2003, Cold Jet acquired Alpheus, a competing dry ice blasting machine manufacturer.[14] In 2016, the company acquired IceTech, a Danish manufacturer of dry ice blasting and dry ice production machines with operations in Denmark and Poland, which Cold Jet continues to operate.[15] In 2022, Cold Jet acquired the dry ice production and CO2 recovery product lines from Aquila Triventek, adding small-volume pelletizers and CO2 recovery units to its portfolio.[16] Also in June 2022, Cold Jet received a minority investment from Seidler Equity Partners.[17][18]
COVID-19 vaccine distribution
During the COVID-19 pandemic, Cold Jet supplied dry ice production equipment to Pfizer and other pharmaceutical and logistics companies to support global vaccine distribution.[19][20][21][22] The Pfizer–BioNTech COVID-19 vaccine required storage at approximately −70 °C, necessitating dry ice for transport and temporary storage.[23][24][25][26] Cold Jet's dry ice production machines were deployed at pharmaceutical packaging lines and global logistics distribution centers throughout the vaccine cold chain.[27][28]
Technology
Dry ice blasting
The dry ice blasting process, also known as dry ice cleaning, uses recycled solid carbon dioxide (CO2) pellets or microparticles that are propelled at supersonic speeds toward a surface.[29] Upon impact, the dry ice sublimates, changing directly from a solid to a gas, which lifts contaminants from the underlying surface without leaving residue or secondary waste.[30]
Dry ice blasters are used for industrial cleaning, surface preparation, and parts finishing to remove burrs and flash. The technology is used across multiple industries,[31] including aerospace,[32] automotive detailing and restoration,[33] food and beverage,[34][35][36] plastics,[37][38] restoration and remediation,[39] and semiconductor manufacturing.[40]
Dry ice cleaning is also used in historical restoration.[41] Cold Jet dry ice blasting equipment was used by conservators at the Mariners' Museum in Newport News, Virginia, to remove marine corrosion from the recovered turret of the USS Monitor.[42][43]
Dry ice production
The dry ice production process uses pressurized liquid carbon dioxide (LCO2), which is expanded in a chamber to form carbon dioxide snow. This snow is then compacted under high pressure by a dry ice production machine to form high-density dry ice pellets, nuggets, or slices.[44]
Dry ice production equipment enables on-site production of dry ice, which can be used for dry ice blasting, cold chain management, and temperature maintenance in food processing applications. Machine types include pelletizers, which utilize liquid CO2 to produce high-density dry ice pellets, as well as reformers and slicers that convert dry ice pellets into blocks or slices.
Dry ice production systems are used globally by food processing,[45] food home delivery,[46] pharmaceutical,[47] industrial gas,[48] and logistics companies[49] for cooling during transport and processing.
